and, as is stated by M. Guenee, is divided iutcrnally iuto two parts, with the ex- 

 ternal surface perfectly smooth. He considers that the sound is produced in a 

 pcrfectlyranalogous manner to that of the Chelonia, viz., by the action of the pos- 

 terior thighs. 



The memoir throughout shews most profound research, and should be carefully 

 studied by all who take an interest in something more than the forming of coUcc - 

 tions ; indeed, it proves most strongly how a collection should be subservient to 

 higher purposes, and not be admired only for its extent. 



The paper winds up with some considerations on the natural position of C. 

 pudica, and the author advises the separation of the species fi-om its congeners, on 

 the same grounds that sepai'ate Setina, from Lithosia, proposing the generic term 

 Tympamphora. — E. McLachlan, Forest Hill, July Mh, 1865. 



Flower-frequenting spiders. — I have lately taken more notice of these. A white 

 species is very common on the flowers of the ' ox-eye,' and sometimes frequents 

 the wild roses ; another I saw on an orchis, but it hid between the blossoms. 



They often had hold of a large fly, or even of a bee, which they had sm-prised 

 at the flower ; and one day noticing on a flower of one of the yellow vetches an 

 example of Vanessa urticce, with its wings spread out, which did not seem to move 

 on my approach, I looked more closely, and found that it was held by the head by 

 a lai'ge bright yellow spider, of almost exactly the colour of the flower. — C. G.

Exeter Naturalists' Club. — At a meeting of this useful society, held at 

 Exmouth on the 24th June, Mr. D'Urban read some Entomological notes, which we 

 present to our readers in a condensed form. 



With reference to the record of the capture of a single specimen of Bhyssa 

 pcrsuasoria near Exeter, by Mr. D'Orville (Ent. Mo. Mag., vol. I., p. 262), 

 Mr. D'Urban mentioned that he had met with the species in fir plantations near 

 Strete Raleigh, and that it was common at Newport. In connection with this, he 

 exhibited two Canadian species of Bhyssa, measuring six inches in length. These 

 were R. necator and B. lunator. The first is common near Montreal, and he had 

 caught many females which were fixed, through having di'iven their ovipositors so 

 far into the wood that they were unable to withdraw them. In many trees these 

 hair-like instruments might be seen sticking out from the trunks, the insects having 

 either broken them off in their eflbrts to escape, or they had been left when their 

 owners had been seized by birds, &c. 



Chrysophomus dispar. A specimen was exhibited which was picked up dead 

 amongst sedges at Slapton Lea, by Mr. Wentworth Buller. 



Argynnis Lathonia. Several examples (one of which was exhibited) were cap- 

 tured about twelve years since at Bystock, also by Mr. Buller. 



Mr. D'Urban also exhibited a specimen of Sphinx ligustri, with pollen masses 

 of an Orchid attached to its right eye.
